About Me
I’m Matija Pozojevic. byHrast collects the tools I build for astronomy; HrAstro is my personal astrophotography site. When I’m not imaging, I’m usually writing PixInsight scripts or tinkering with ASCOM gear.
Feel free to explore the projects and get in touch if you want to talk about any of them.
